Early diagnosis (currently 7 weeks) ? Looking for your Suggestions? Feeling scared

Hi everyone I am 35 second time pregnant. First pregnancy 4 years ago I had GD. Then I got prediabetes for last 3 years. My a1c 6 months was 5.7 with metformin, but my primary care asked me to stop metformim as soon as I got pregnant.

I am currently just 7 weeks pregnant but just started wearing a CGM to track my blood sugar. OMG it has been scary, my blood sugar fasting is around 115 and everything even without much carbs is spiking me a lot. I want to give examples of yesterday meals

Fasting - 115

morning I had half avocado, 2 eggs, 1 cheese and 4 watermelon cube, after an hour 141.

Lunch I had 1 chapati, some veggies and siggis yogurt for protein and it was 155 after 1 hour

Dinner I had modest amount of rice with fish curry and it was 202.

Last pregnancy, the dinner would have spiked me but lunch and breakfast would have kept me in range. These numbers are looking insane to me.

I have just called my gynec office and waiting for call back but these numbers are scaring me.

While I wait, I am looking for suggestions in this community about what helped you guys? Did you start taking insulin early? What should I do as my next steps.

Thank you!
